PHILIP C. WEN'IWOR'IH, OF PROVIDENCE, RHODE ISLAND.

RING TRAVELER. 7

Application filed January 17,1924. Serial No. 686,854.

Be it known that I, PHILIP C. ENT- WORTH, a citizen of the United States, residing at Providence, county of Providence, State of Rhode Island, have invented certain new and useful Improvements in Ring Travelers, of which the following is a specification.

In my previous Letters Patent No. 1,- 461,059, July 10, 1923, I disclosed and discussed a new traveler and method of making the same, the invention having particular reference to the production of a greater hardness in the terminal horns of the traveler as distinguished from the intermediate or so-called bow portion.

My present improvement relates to a new form of traveler in accordance with this invention and one which has great adaptability and great importance.

In travelers for certain kinds of work the particular form shown in my previous patent is sometimes unavailable particularly for very fine work but the variable temper is none the less very important and desirable. The object of my present invention is a traveler having the characteristic hardness or temper of-my former invention but capable of production even in very small sizes. 7

I have found that it is possible by variantly reducing the width of the bow portion of the traveler blank to obtain in a finished traveler an article of different shape but of the same general'characteristics as that heretofore described by me. I am aware that it has been proposed to make a traveler having enlarged and thickened horns by which somewhat the general appearance of my present traveler was presented but it was not contemplated as far as I am aware in that or in any other traveler to provide it with a differential temer. p As illustrative of my invention I have shown in the accompanying drawings a simple form of high efiiciency and one well adapted to meet a range of requirement heretofore difficult to fill. Throughout the specification and drawings reference characters are employedafter the usual manner, and in the drawings:

Fig. 1 is a side elevation of a traveler in accordance with my invention.

Fig. 2 is a plan. view of the same, and

Fig. 3 a central section on the line 8 3, Fig. 1.

Such a traveler comprises a bow portion B and terminal horns H and is preferably produced from a strip of stock of uniform width and thicknessand having uniform low carbon content as in accordance with my previous patent. The strip of stock which forms the flat blank from which my traveler is made is provided on each side of its bow portion with a long smoothly rounded symmetrical scallop S by which the naturalwidth of the metal blank'may be narrowed to any desired amount.

The amount of metal therefore in the region of the bow diminishes from the area of :the horns variantly towards the center of the traveler. From the blank solformed the traveler itself is built up after the usual manner and then treated to increas its carbon content. The travelers may bepacked in layers in any suitable carbonizing material such as bone black and heated in a fur nace for some six or seven hours to assure as complete an absorption of carbon by the metal of the traveler as is possible through out the entire traveler. The travelers are then withdrawn and quenched and at that stage are extremely hard but correspondingly brittle. The travelers are then subjected to a slow heat by which the temper is withdrawn and in this action. the bows beingof lesser diameter respond more rapidly to the treatment. Under the tempering heat the carbon begins to recombine more'quickly in the bows and by suitably timing the tem- V pering a maximum degree of hardness may be retained in the horns while the carbon in the bows may be considerably recombined so that upon quenching they will be found to have a maximum hardness at the horns and a very considerabl resiliency at the bows.

For the purposes of this application I shall discuss my invention in its relation to the ring traveler of the horseshoe type, comprising. terminal horns and a connecting bow. It is to be understood, however, that such treatment is purely illustrative and in no way limiting, and that the term ring traveler is to be construed in its broadest sense as referring to any traveler whether for ring spinning or twisting, which travels about a ring, and so construed to cover either the horseshoe or the vertical type of traveler.

lVhat I therefore claim and desire to secure by Letters Patent is:

l. A ring traveler comprising a bow and terminal horns of uniform thickness throughout, but diminishing in width from the horns towards the center of the bow symmetrically with reference to the longitudinal median line of} the traveler.

2. A ring traveler comprising a bow and terminal horns of uniform thickness throughout, but diminishing in width from the horns towards the center of the bow symmetrically with reference to the longitudinal median line of the traveler, the edges of the bow in said diminished areas being smoothly rounded.

3. A ring traveler comprising a bow and terminal horns, said horns of uniform width and thickness throughout, and said bow of uniform thickness but diminishing in width from the horns towards the center of the bow symmetrically with reference to the longitudinal median line of the traveler.

at. A ring traveler comprising a bow and terminal horns, said horns of uniform width d thickness throughout, and said bow of the same thickness as the horns and being provided on its marginal edges with symmetrically disposed scallops.

5. A ring traveler comprising a bow and terminal horns, said horns of uniform width and thickness throughout, and said bow of the same thickness as the horns and being provided on its marginal edges with symmetrically disposed scallops, said scallops extending continuously from the horns towards the center of the bow.

6. A hardened and tempered one piece ring traveler comprising a relatively soft spring tempered bow and relatively harder terminal horns, said horns of uniform width and thickness throughout, and said bow of uniform thickness but diminishing in width from the horns towards the center of the bow.

7. A hardened and tempered ring traveler comprising a bow and terminal'horns of uniform thickness throughout but diminishing in width from the horns towards the center of the bow, the tempering effect being greater in the bow than in the horns, and the horns having greater hardness than said bow.

In testimony whereof I atfix my signature in presence of two witnesses.
